Sea Spray A seaweed leshy's water jet has enough salt in it to temporarily impair their target's vision. On a hit, the target must succeed at a DC 20 Fortitude save or be dazzled for 1 minute or until it spends 3 Interact actions wiping the salt out of its eyes. On a critical hit, a target that fails its Fortitude save is also blinded for 1 round.
